18 Claims.

The present invention relates to lubricating devices and more particularly to multiple oilers.

An object of the invention is to provide a simple and durable oiler which can be easily assembledY and inexpensively manufactured, which will enable the use of a substantial number of sight feed valves in a limited space, which will permit the number of valves to be readily increased or Idecreased even in the field, which will allow easy replacement of damaged valves, and which will avoid leakage between adjacent gang-mounted valves.

Another object is to provide an oiler which is of rigid construction, which will simplify mounting and facilitate cleaning, and which will re- Vduce flow resistance and afford a supply of clean oil.

A further object is to provide an improved feed valve which can readily be assembled with one or more similar valves to form a multiple oiler.

The invention further consists in the several features hereinafter described and claimed.

In thedrawing, I5 designates each of a plurality of sight feed Valves which are assembled with other parts as hereinafter described to form a multiple or gang oiler. Each valve includes an elongated vertical block-like valve body i6 which is of square cross-section and is formed of a suitable metal, such as an aluminum alloy. The valve body has a transverse horizontal oil inlet bore I7 therethrough adapted to register with similar bores formed in adjacent bodies to provide a manifold passage. The lower end portion ofeach valve body has a large vertical bore i8 which is intersected at opposite sides by horizontal channels I9 of semi-circular cross-section. Axially extending in the bore I3 is a vertical sight tube 26 of glass or transparent plastic seated at its upper and lower ends against gaskets 2i and conned by a bushing 22 screwthreaded into the lower end of the bore. The bushings of the several valves are provided with couplings 23 connected to delivery tubes 24 leading to various machine parts to be lubricated. A vertical bore or orice 25 is formed centrally in each valve body between the transverse bore Il and the upper end of the bottom bore I8. A drip nozzle 26 is secured at its upper end in the bore 25 and has its lower end extending into the sight chamber formed in the sight tube 26. The upper end of the bore 25 has a tapered valve seat 2l'. A vertical needle valve 28 is screwthreaded in a central verticalbore 29 extending in the valve body above the transverse bore Il, the needle valve having a tapered lower end adapted to cooperate with the valve seat 2l, and having a knurled thumb wheel 36 at its upper end. A packing 3i in the valve body surrounds the intermediate portion of the needle valve and is retained by a packing nut 32 which is screwthreaded into the upper end of the valve body and which receives therethrough the needle valve. The needle valve serves to control the rate of Yilow of oil from the horizontal passage llinto V'with flat side'a'ces ofl the bodies. l ends of the rods-areconnected by transverse the thickness of the O-ring, so that the O-ring is placed under axial compression when the oiler is assembled. The other end of the transverse bore Il has -a screw-thread 35 adapted to receive a pipe plug 35 when the valve body is endmost in the assembly. The opposite flat side faces of each valve body are provided with horizontal upper and lower channels 3l of square crossesection arranged l'above and below the plane or" vthe transverse bore il, and adapted to receive retaining means hereinafter described.

A vertically extending block-like mounting body 38 of square cross-section has a reduced, screw-threaded, shoulder-forming lower end portion 39 adapted to pass through af'suitable 'sup'- porting bracket 4Q which is clamped to the-body by a nut 4! on the end portion 5e. The mounting body, which is formed of a suitable metalsuchas `an aluminum alloy, has a central vertical bore 42 closed 'atits upper'and lower'ends by pipe plugs 4 3 and 44, the lower portion of the bore forming a Ysediment chamber, and the lower plug 44 fornii'ng'a drain plug. A transverse bore' intersects the vertical bore l2 and is aligned with the `transverse boresk il of the several valve bodies.

In 'some instances, the opposite ends of the bore 45 may be provided with screw threads rif. 'A lateral, screw-threaded oil inlet borefliq communic'ates with the upper portion of the'vertical bore V42, and is supplied with oil as hereinafter described. At opposite sides of the mounting body "are a pair or horizontal channels 3 of square cross-'section aligned with the corresponding channels 3l of the valve bodies. A pair or" vertically extending bloclr-like spacer bodies 'de of Vsquare cross-section, and formed of-a suitable metal, such as an aluminum alloy, are disposed at opposite 'sides or" the mounting body and between the mounting body and the nearestvalve bodies. Each 'spacer bodyhas a transverse bore 5Fl aligned with the valve body bores il and the mounting body 'bore @35. At one end of the transverse bore offeach spacer body is a ccunterbore'l adapted toreceivean' O-ring 3d to provide a sealing en- A between the spacer body and the `Vmounting body. IAt the other end of the'trans- ,verse vbore 5d vis a'screw thread 52 which is vadapted 'to'be'closed by a screw plug (not shown) fin the 'absence of an adjacent valve body. At cp- "pojsite sides of each spacer body are a pair of parallel channels- 53 aligned with the similar vchannels of the mounting body and ythe valve bodies. vThe valve bodies, spacer bodies 'and :mounting body `are all of the same cross-sectional "area'and are conveniently formed from square "bar stock. 'By way of example, in a typical oiler these `bodies maybe formed oi bar stock '7/8 square.

"The'typical multiple oiler shown inthe draw- "ing includesa series 'of three sight feed valves 'at each of the opposite; sides of the mounting body,

'but'it will bev'understood that any reasonable 'number 'of valves maybe provided. It is preferred 'to `have at least 'one'valve at each side o-'the 'mounting body, butin someinstances the valves maybe Vdisposed'entirely at one side o the mount- 'ingbody, and the` opposite spacer block may be omitted. The Vseveral block-like bodies are held Ain laterally abutting assembled relation retainingrneans including four rods or bars54 of square crosssectionjtting in the aligned lateral grooves or/channels 3l," d3, 53 formed in these bodies,'the outer side faces of the rods being flush The opposite 5,0 ing member.

clamping plates 55 laterally' engaging the end-A most bodies and secured to the rods by screws 55 passing through holes 55 in the plates and threaded into openings 54 extending axially in 5 the ends of the rods, the screws being provided with lock washers 5l and the rods being slightly shorter than the length of body assembly or stack. In assembling the several bodies, the tightening of the screws vEifwill axially compress the several lo v'O-rings and bring the `adjacent flat vfaces of the bodies into iirm contact, the O-rings sealing the joints between the bodies against leakage.

'Gil is supplied to the inlet opening il of the mounting body from a suitable oil reservoir 53 5 'here -showh 4to include a transparent tubular casing Amember y5S of glass or plastic fitting against gaskets AGli in upper and lower heads El and '62, the upper head having a filling nozzle 53. The heads are connected by a central vertical tube 456i which is screwed at its lower end into the lower head and is screwed at its upper end into a headed bushing 65 rotatably fitting in ithe upper head. The lower head 62 has a downwardvly :projecting screw-threaded boss Gd with acentral outlet bore di. In some instances, the-resenvoir may be provided with a'rnanually operable needle valve 33 of conventional spring-closed type which extends axially-mathe ktube-iid to y.cooperate with the bore lil, the valve having at its upper end the usual toggle lever 68 bearing on the upper face of the bushing E5. The boss 56 is threaded into the recessedv upper endoi a control valve body 59. A ter screen'or sieve Se is conlined the recessed upper endet" the valve body 35 69 and vis disposed between packing Yrings ll.

rihe valve body als has a recess l2 in its lower end which communicates with the upper recessed end of the body by a longitudinally extending boreal?, arrangedfeccentrically in the body. A discharge port 'l extends centrally upwardlyl from the bottom recess l2 and has a valve seatl at itslower end. The upper end of the dischargel port ecmrnunicates withfa recess l-opening laterally of the valve body. A horizontal tubular coupling 3 member 'll is screwed at opposite ends into the recess l'e and the lateral openingfll lof the mountiing member 38 to provide communication between the control valve bcdyand the mounting member and to support the oil reservoir from themount- A solenoid l5 is screwed into the bottom recess l2 of the control valve body-and has-'an upwardly spring-urged valve member l5: which is engageable with the valve seat l5 to close the discharge port 'E When the solenoid is energized the valve member `l5 is retracted downward to expose the discharge port, thuspermitting oilA to iow by gravity from the reservoir to the mounting bodyV 33 and thence through' the transverseboresof the spacer bodiesilandthe several sig t feed valve bodies l5. The solenoid rwindingof theccntrolivalve Vis 'connected-in a suitable control circuit, not shown, so as -to-'be energized whenever' a machine served'by ftheoiler is in operation. rIhe valve seat l5 of thecontrol valveisat'an elevationnot farfrom thev elevation of the oil 'passages valves.

In'some installations, air trapped in the deil 'in' the sight` feed 0 livery tube'Zll extending from a sight feed valve may prevent proper feeding of -oil through the "tu-be. v.ln-such case, a small passageli, Fig.' 3, 'isfformedin 'the' valvebodyfi and extends upwardly from the chamber in the 'sight tube 20 to"formV an air vent. -AAs an alternative a venting 'notch 8I may vbe formed in the ipp edge of the sight tube.

1 In the operation of the multiple oiler, the solenoiol valve 'i8 is opened when the machine (not shown) is started in operation, permitting oil to flow by gravity from the reservoir 58 through the outlet bore 6l, screen 10, passage 'I3 and discharge port 'I4 of the control valve body, coupling member ll, vertical bore 42 and horizontal bore 45 of the mounting body, the transverse bore 50 of each spacer body, and the aligned transverse bores I1 of the several valve bodies. The downward feed of the oil from each valve body is adjusted by the needle valve 28 and is observed through the sight tube 20. When the machine stops the solenoid valve I8 closes, thus shuttingoff the flow of oil.

The several sight feed valves I5 are interchangeable, and a considerable number of these valves can be included in the oiler assembly, it being only necessary to provide retaining rods or bars 54 of suitable length. It is also possible to add or remove valves in the eld to suit requirements, and any damaged valve can be readily replaced. The lower end portion of the vertical bore 42 in the mounting body forms a sediment chamber which can be drained by removing the screw plug 44. The horizontal manifold passage through the block-like bodies of the oiler assembly can be cleaned by inserting a cleaning implement therein after removing the end plugs 36 and raising the needle valves 28.

In some instances the square retainer bars 54 for the oiler assembly may be replaced by a channel member 33, one being shown in Fig. 12. The channe1 members have bar-forming ilanges 84 which t in the horizontal grooves or channels of the several bodies of the oiler assembly, and the ends of the flanges have screw-threaded openings 84 to receive screws 56, as in Fig, 5.

The modied form of valve assembly shown in Figs. 13 and 14 includes a pair of sight feed valves II5 which are generally similar to the valves I5. Each of the valves II5 has a valve body IIS provided with a transverse through bore Il and with shallow frusto-conical -counterbores |33 at opposite ends of the bore II'I. The confronting counterbores of the abutting valve bodies receive and compress therein a sealing O-ring 34. The two (or more) valve bodies are clamped together in the same manner as the assembly of Fig. 1, except that the channel members 83 of Fig. 12 are provided, and the spacer Vbodies and mounting body of Fig. 1 are omitted. lHowever, the square bars 54 could equally Well be provided in the assembly of Fig. 13. The valve assembly is supported on an oil inlet pipe |38 which is threaded into the end of the transverse bore of one of the valve bodies. The bore at'the opposite end of the assembly is closed by va plug 36. The transverse bore I'I of each valve bodyhas a'screwthread 52 at one end or at each end.

The oil may be supplied to each form of oiler Yeither by gravity. or pump pressure. In the form of oiler shown in Fig. l, the incoming oil may be introduced at any one of various points, such as the upper and lower ends of the mounting body bore 42 or the opposite ends of the manifold passage formed by the bores Il. It is also possible to supply oil to each oiler assembly by connecting it to a circulating oiling system.
